A) Reflection over the x-axis
B) Translation 10 units left and 4 units down

- 6. Find the rate of change and the y-intercept for the table shown.
A) m = 8; b = -3
B) m = - 8; b = 3
C) m = 3; b = - 8
D) m = -3; b = 8
- 7. A cooler contains 3.5 gallons of water and is filling up at a rate of 0.1 gallons per second. A second cooler contains 7 gallons of water and is draining at a rate of 0.25 gallons per second. Write and solve an equation to determine the number of seconds, x, it would take for each cooler to contain the same amount of water.
A) 3.5 - 0.1x = 7 + 0.25x; x = - 10
B) 3.5 + 0.1x = 7 - 0.25x; x = 10
C) 3.5x + 0.1 = 7x - 0.25; x = 0.1
D) 3.5 + 0.1x = 7 + 0.25x; x = - 23.3
